ATTORNEY Patented Oct. 15, 19 29 UNITED- sir-Arias WELLS S. FLEMTNG, OF PORTLAND, OREGON moon DRAIN Application filed July 22,

This invention relates to improvements in floor drain fittings adapted for use with shower baths and the like.

The object of the present invention is the provision of a floor drain of simple and practical construction which is adjustable for installation in floors of various-thicknesses and to which a sheet of waterproofing material may be connected in watertight condition by simple and homogeneous devices Without the employment of bolts or screws. I

Other objects andadvantages of my invention, and objects relatingtodetails of construction and arrangement of parts', will be readily apparent in the course of the detailed descriptionto follow.

i The accompanying drawings illustrate by way of example one form in which my invention may be embodied, in which:

Fig. Iis aview i i-vertical section of a floor drain embodying my inventionset'in' operative position; the section being taken 'on the line'1-1 of Fig; 2. y i V Fig. 2 is a plan of my floor drain showing the water-proofing sheet clamped in place. and this view being partly in section on the broken line indicated by 2-72 in Fig. 1.

Figs. 3 and 4 are perspective viewsof elements of the invention. I

Referring to said views, the reference numeral 1 indicates a cylindrical body of my.

improved floor drain having a bore 2 extending vertically therethrough. The lower end of. said bore is provided with screw threads 8 with which the end of the waste or drain pipe, not shown, may be connected.

Said body extends upwardly in a hub 4 through which the bore 2 extends and is provided with internal screw-threads 5. A circular flange 6 extends in substantially horizontal directions with a relatively slight upward angle to aflord drainage toward the bore 2, the cylindrical wall of the body being formed with slotted openings? extending upwardly from the horizontal line of the upward face of said flange. Said upper face of the flange is recessed, as at 8, leaving an in clined wall 10 at its marginal ed 'e.

An annular plate 11 is provided of configuration to set within the recess 8, and a sheet 1923. Serial No. 124,187-

of waterproof material 12, such as sheetlead, tarred paper, or thelike, is laid over the flange 6 and is secured thereto by the plate 11 by -means to be presently described and may extend over as large an area about the drain fitting as deslred.

Said'plate is formed with a central circular opening to admit of its being fitted over the cylindrical body 1 of the fitting and about said opening. Said plate is provided with an annular integral collar 13 which is pierced with a plurality of radially directed apertures 15 equal in number and spacing to said slotted openings 7 in the body wall.- 7

' The hub 4 above the plate 11 is externally threaded, as at 16, with which anut 17-is engaged. Said nut is formed with. hexagonal faces to'recelve a wrench and 1s designed to V be'screwed' upon the screw-threads 16 to bear on the collar '13 and press the plate 11 toward: the flange ,6; with the waterproof sheet 12 *therebetween to make a reliable Watertight joint.

18 'ind1cates a drain section comprising a tubular portion 20and a funnel shaped upper 7 fend'21." The tubular portion 20 is formed with external screw-threads interfitting with the screw-threads 5' of the drain bore and whereby the drain section may be adjusted to any'elevation. The'upper end of the funnel portio'n 21'; is provid ed' with a grille-plate 22 idsignfd to' be adj usted to the level of the lfi'oon'in which the fitting'is set. To insure that theplate 11 wlll not move in rotary directionswhen the nut 17 is screwed jclown'thereupon, I provide a' notch 23 upon the innercircumference of the plate 11 into which a lug-25 extending'laterally from the exterior of the body wall 1 is-adapted to interfit. Said notch and lug are so positioned-v that when in engagement the apertures 15 and slotted openings 7 will be in register.

The clra in body 1' may be set upon the subfloor 26 of the building in which it is installed, and the waterproof 'sheet 12 is laid over the flange 6, circula'rportion being cut out-to admit of its being centered over'the body portion of the fitting; The plate .11

-may then be mounted in position and the nut 17 screwed down thereupon, which will cause the flange and the plate 11 to be drawn together to firmly squeeze the waterproof sheet 12 therebetween in watertight condition, the drain section 18 being mounted in operative position and to suitable elevation to bring it to the level of the intended floor. The superficial floor 27 of plastic or other similar material may be laid in conformity therewith,

Having described my invention, what 1 claim, is:

1. A floor drain comprising a body having a tubular portion and a laterally extending circumferential flange, an annular plate seating on said flange, said plate provided with a slotted hub about its central hole, the flange'and said plate being adapted to have a sheet of water-proofing material interposed between them, the said tubular body portion extending above said flange and said plate, the upper end of said tubular portion having an external thread, and a nut threaded on said upper tubular portion, said nut bearing on the hub of said plate, whereby to press the latter firmly upon the water-proof sheet placed upon said flange. v

2. A floor drain comprising a body having 1 a tubular portion and a laterally extending cupped circumferential flange, an annular plate seating on said flange, sa1-d plate provided with a slotted hub aboutits central hole,

the flange andsaid plate being adapted to e. have a sheet 01": water-proofing material interposed between them,-the said tubular body portion extending above said flange and said plate, the upper end of said tubular portion having an external thread, said upper end of i said body portion provided with slotted openings, adapted to register with the slots in said hubof said flange, and "a nut, threaded on said upper tubular portion, said nut bearing on V the hub of said plate, whereby to press the latter firmly upon the, water-proof sheet placed upon said flange. -v v 3. A'floor drain comprising a body having ing cupped circumferential flange, an annular plate seating on said flange, said plate provided with a slotted hub about its central hole, the flange and said plate being adapted to have a sheet of water-proofing material interposed between them, the said tubular body portion extending above said flange andsaid plate, the upper end otsaid tubular portion having an external thread, said upper end of said body portion provided with slotted openings, adapted to register with the slots in said hub of said flange, a nut threaded on said upper tubular portion,

said nut bearing on the hub of said plate,

v body portion extending above said flange and said plate, the upper. end of said'tubular portion having an external thread, anut threaded on said upper tubular portion, said .nut bearing onthe hub of said plate, whereby to press the latter firmly upon the waterproof sheet placediupon said flange, a drain section adjustablymounted insaid internal screw threads of said body portion, and means to prevent circumferential movement of said plate on said flange,
